phpMyFAQ from 4.0.0 before 4.1.9 contains an incorrect authorization vulnerability that allows delegated admins lacking the editnews right to modify news by calling PUT /admin/api/news/update, which checks NEWS_DELETE instead of NEWS_EDIT. Attackers holding addnews and delnews can read the update-news CSRF token from their own cookie and rewrite any news item's header, body, author, link and active flag shown on the public front page.
